Document how to integrate in pre-commit with plugins

Environments:

• Prettier Version: 1.19.1
• Running Prettier via: pre-commit
• Runtime: node v12.13.1
• Operating System: Linux

Steps to reproduce:

All I want to do is to integrate the prettier-xml plugin into pre-commit.

I tried with this, but it doesn’t work:

  - repo: https://github.com/prettier/prettier
    rev: "1.19.1"
    hooks:
      - id: prettier
        name: prettier xml plugin
        additional_dependencies:
          - "@prettier/plugin-xml@0.5.0"
        args:
          - --with-node-modules
        files: \.xml$

Expected behavior: Reformat xml files

Actual behavior:

Running pre-commit run -a:

prettier xml plugin......................................................Failed

Workaround:

Configuration from https://github.com/prettier/plugin-xml/issues/17#issuecomment-555445966 works, but I guess that’s not what you want to recommend to use.

fixed by https://github.com/prettier/prettier/pull/7508

This works for me:

- repo: https://github.com/prettier/prettier
  rev: "2.0.2"
  hooks:
    - id: prettier
      additional_dependencies:
        - "@prettier/plugin-xml@0.7.2"
      args:
        - --plugin=@prettier/plugin-xml
      files: \.xml$
